find a couple that are into sharing the wife also and see if your wife would be interested in chatting with you and them together.
Well I would buy (unless you already have)
Sex toys. Realistic cocks and role play. Have her ride the cock on the floor while she sucks your cock. Ask her how she likes it and ask if it turns her on. You can do other things like have her wear a blindfold and pretend she’s being done by you and another guy. Have her suck your cock and the realistic one, then lay her down and fuck her with the cock while she sucks on your. If you keep doing these role play she’ll be so turned on by the thought in no time
We are finding hard to find a couple we can have a social relationship with, where my wife and the husband are able to enjoy an ongoing exclusive sexual relationship with each other and their own partner only. It would be much safe for a husband interested in an other woman or this life style and a wife that had no interested in being with an other man sexually.
